Wheeze is the musical continuous sound produced by oscillations in any critically narrowed airways, and heard mostly on expiration. It is common in preschool age, about half of all children will experience an episode of wheezing by their sixth birthday. Asthma is usually characterized by cough, wheeze, chest tightness and fast breathing. It is a significant global health issue and affects both children and adults. The prevalence is on the increase, especially in LMIC. Studies from different populations have revealed the key role influencing the progression from preschool wheezing to childhood asthma. Recurrent wheezing is four or more episodes in the preceding year and has a spectrum of phenotypes and with heterogeneous features. Phenotypes of wheezing were proposed to facilitate the identification of young children who are at risk of subsequent development of asthma. The epidemiology and environmental determinants of recurrent wheezing and asthma are discussed.

In this prospective cohort study with 2326 hospitalized children and young people with coronavirus disease 2019 in Spain and Colombia, 36.4% had comorbidities. Asthma, recurrent wheezing, chronic neurological, cardiac and pulmonary diseases significantly increased the risk of severe outcomes such as death, mechanical ventilation and intensive care unit admission.

Aims: We investigated sensitization to food allergens as a prognostic factor for wheezing in children with recurrent wheezing and compared serum club cell 16 (CC16) and surfactant protein D (SP-D) among these children with and without sensitization to food allergens.
Materials And Methods: Children with recurrent wheezing were enrolled in this prospective cohort study. Specific IgE to five common food allergens (Fx5) was assessed at baseline, and children were followed-up for 1 year for new-onset wheezing episodes.

Introduction: Throughout the perinatal period children are exposed to complex mixtures, including indoor chemicals such as phthalates, and biological agents. However, few studies focus on interactions between early-life co-exposures to shed light on how co-exposures modify their individual effects. Therefore, our study aims to assess whether early-life exposure to pets and related biological agents, namely pet allergens and endotoxin, modifies the association between di-(2-ethylhexyl) phthalate (DEHP) and asthma and wheeze in preschoolers to gain insight into interactions.

Background: Evidence is mounting that domestic use of disinfectants and cleaning products (DCP), particularly in spray form, is associated with wheezing in children. Beyond the home environment, many children are also exposed to DCP in daycare. The links between daycare exposures to DCP and child respiratory health have never before been studied.
